Application filed November 26, 1917; Serial No. 204,039. Renewed January 11, 1919.

To all whom it may concern:

Be it known that I, GEORGE B. Mormon, a citizen of the United States, residing at Spokane, county of Spokane, and State of Washington, have invented certain newand useful Improvements in Hydrocarbon- Burners, of which the following is a specification. f

The present invention relates to improvements in hydrocarbon burners, designed especially for use in burning or firing treestumps when clearing the ground of trees.

The customary method at present in vogue is to pile inflammable material about the tree stump to be burned, after having bored or drilled holes in the-stump to form v lines or passages so that the flames maypenetrate the interior of the stump, and thus more quickly consume the tree stump. The flues in the stump, whichusually open at the ground, or into a recess dug below the ground line, form draft passages for the flames to enter from the fire built about the stump, and of course the flames consume the interior as well as the exterior of the stump.

The primary object/of the present inven-" tion is to provide a burner which may be handled quickly and with facility, which is simple both in construction and operation, and which will direct the flame into the holesin the stump with intensity in order that the stump may be quickly consumed. The burner device may of course be used in conjunction with the usual pile of inflammable material, or in some instances, may be utilized exclusively of other firing means.

Figure 1 is a side view of a burner device constructed and operated according to the present invention.

Fig. 2 is a view, illustrating the applica tion of the invention to a tree stump, telescopic supports or legs being brought into use to hold the burner in fixed position to the opening bored in the stump of the tree.

Fig. 3 is a top plan view of the device with the swiveled telscopic legs folded in position out of use as in Fig. 1.

or tube for supporting the oil and water supply pipes.

Fig. 6 is an enlarged detail of the connection ofparts between the two tanks.

Fig. 7 is an enlarged detail view of the adjustable supports or telescopic legs for the casing.

Fig. 8 is a sectional detail'view of oneof the several burner nozzles and tip.

In the preferred embodiment of the invention as illustrated in the drawings, a pair of cylindrical, closed metallic tanks of usual construction are employed, tank designated l being for hydrocarbon, as kerosene, and tank 2 being a container for water. A hand pump 3 is preferably utilized to create pres.

kerosene and water through the supply pipes 7 and 7 respectively, which are connected to the tanks in suitable manner and provided with flexible portions or bends 7 before'they enter the open end of the tubular casing or large pipe 8. In order that this casing and its contained supply pipes may move relatively to the two tanks, a flexible or hinged joint is provided through the instrumentality of the pair of trunnions 9 9 projecting from the sleeve 10 fixed on-the end of the casing and into which the s pply pipes en ter, as in Fig. 5.

The trunnions are supported between the adjoining tanks by means of a pair of straps 11, 11, curved to conform to the periphery of the tanks and each formed with an annular rod or bar 12 pivoted to the strap, and

formed at its free end with threads to recelve a wing nut'as 13; The threaded end of the bar is passed through the free end of the ,strap, and the wing nut is employed to clamp the entire strap and rod on the tank as will readily, be understood. Thus the easing and contaned supply pipes may be swung on a pivot relatively to the tanks, and by this means the casing may be adjusted to suit different circumstances and conditions.

To support the casing and supply pipes, an adjustable support is fashioned of a pair of telescopic legs 14, laterally swiveled at 15, and hinged at 16 longitudinally of the easing, so that the legs may be lengthened or shortened independently of eachother, and may be swung either laterally or longitudi nally, independently of each other, to adapt them to the irregularities hold the casing supply pipes and burner in adjusted position.

Theremote or free end of the casing is fashioned With a head 17 provided With having attached thereto the cylindrical open mouth;

'tions in its head, and Within low plug, head or tip 24 the supply pipes 7 and 7, and shell or shield 18, of metal, and provided With an The supply pipes 7 and 7 are the shield through perforathe shield the coiled about its Walls, as indicated openings for introduced into pipesare at 19 and coils for the kerosene and Water from'thelr tanks. Within the shell or shieldand secured to the head thereof, are apair of vessels 21 and 22' forming generating chambers for gas and steam, and each of the ormed or provided With an a threaded," holthe jet- A flash,

The number of nozzles and tips may be "varied" to furnish various degrees of heat,

and the tips maybe adjusted .in the nozzles by turning on their threads. It Will be noted that the tip project-s Well Within the interior of the nozzle so that sediment or eX- tra-neous matter that may settle in the bottom of the nozzle is not likely to clog up the tip opening Within the nozzle, and should such stoppage occur, the passage may be opened With a fine Wire.
